BLOWER AND SMOKE CONSUMER Filed April 2, 1928 win 66/757221?! INVENTORATTORN EY Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE GIOVANNIDINARDO, OF PHILADELPHIA, AND JOHN CEFFARATTI, OF DAR-BY, PENNSYLVANIA'BLOWE-LB, AND SMQKE CONSUMER Application filed April 2,

The present invention relates to an improved blower and smoke consumer,and a purpose of'the invention is to provide a device of this kind,wherein it is the object to not entirely absorb the smoke, but toprevent the black smoke from soft coal discharging its contents into theair over a large area, and at the same time create substantial draft atthe base of the stack, especially the stack of a locomotive, though notnecessarily, as the present invention may be used on other stacks.

Another purpose is to provide a blower and smoke consumer especiallyadapted for use on the interior of the stack at the base thereof andnear the top of the stack, the base section of the device constitutingthe blower proper, while the upper sections, though they have blowingcharacteristics, that is to create a draft, constitute the consumer, theseveral sections of the device varying in diameter, the base sectionbeing the larger and acting to create a draft close to the inner surfaceof the wall of the stack, the second section being less in diameter anddesigned to create a draft near the center of the stack, while theupper-most is still smaller in diameter and designed to create a draft,the three drafts being what is turned force drafts,

leaving the stack in cylindrical formation, said columns of draft beingone within the other, acting to carry the smoke to a considerable heightfrom and above the stack. In this manner the black smoke such as soot,

dirt and the like, receiving a dampening action from the steam, whichcreates a consuming action and particularly carrying the smoke asubstantial distance in the air, preventing it from being scattered overa very 40 large area.

Still another purpose is to provide the lower section of the blower andconsumer with outlet nozzles that will create very fine sprays of steamthrough the stack, acting to create a substantial draft and at the sametime absorb the smoke.

It is to be understood that the particulars herein given are in no waylimitive, and that while still keeping within the scope of the 59invention, any desired modification of details 1323. Serial No. 266,810.

and proportions may be made in the construction of the applianceaccording to circumstances.

The invention comprises further features and combination of parts to behereinafter set forth, shown in the drawings and claimed.

In the drawings Figure l-is a view in section of a portion of alocomotive showing the smoke stack and illustrating the improved blowerand smoke consumer applied, one section thereof being at the base of thestack and the other two sections adjacent the upper end of the stack.

Figure 2'is a plan view of the same.

Referring to the drawings, 1 identifies the flower and smoke consumer asa. whole, which consists of the base section 52 disposed at the base ofthe stack 3. This base section is in the form of an annular or circulartubbing connected to a T 4, which in turn connects to a pipe section 5,which in turn operatively connects in any manner with a source of steamsupply. As an example this pipe section 5 may connect with the steamchest, so as, to conduct steam under pressure to the blower and smokeconsumer.

The pipe section 5 includes a T 7, to which an upstanding pipe section 8is connected. The upstanding pipe section 8 has a cook or valve 9 forcontrolling the flow of steam through the upstanding pipe section.

The circular base section 2 of the blower is provided with a pluralityof upstanding outlet spray nozzles 10, which act to discharge aplurality of sprays of steam upwardly through the stack and adjacent theinner surface of the wall of the stack, and which steam acts to absorbthe black smoke and soot, and at the same time discharge the smoke ingeneral from the stack in a cylindrical contour, or in a tubularformation, as the smoke emanates from the top of the stack.

The upper part of the pipe section 8 has a T 11, which is connected to asecond T 12 by means of a nipple 13. A circular or annular blower andsmoke consumer section 14 is connected to the T 12, and is provided witha plurality of discharge nozzles 15, acting to discharge a plurality ofsprays of steam upwardly through the stack, that is at the upper end ofthe stack and a substantial distance from the inner surface of the wallof the stack. This second discharge of steam in sprays is also intubular formation or cylindrical arrangement in a diameter much lessthan the spraying of'the first spray of steam from the base section.

The extreme upper end of the pipe section 8 has an elbow 16 connected toa T 17 by a nipple 18. The T 17 also has a smoke consumer pipe section19 of a diameter much less than the smoke consumer section 14, and thissection 19 has a plurality of discharge nozzles 20, discharging aplurality of sprays of steam in tubular or cylindrical formation, saidformation being of substantially less diameter than the first and secondblower and smoke consumer sections.

The arrangement in construction of this device discharges a plurality ofcylindrical formations of sprays of steam, one formation being withinthe other, acting to blow the smoke and soot from the stack, the blacksmoke and soot being absorbed and causing the smoke to discharge asubstantial distance above and away from the stack, preventing suchsmoke from spreading over a substantially wide area.

The invention having been set forth, what is claimed is:

1. A blower and smoke consumer for a stack, comprising a blower sectionwithin the stack adjacent its base, said blower section havingconnections with a steam supply, upper blower and smoke consumersections within the stack adjacent its top having operative connectionswith the source of steam supply, and means intermediate the upper blowerand smoke consumer sections and the base section, whereby the steam maybe cut off from the upper blower and smoke consumer sections, saidblower and smoke consumer sections decreasing in diameter from the basesection to the uppermost section, whereby a plurality of cylindricalforms of steam sprays one within the other may be discharged through thestack.

2. In a blower and smoke consumer for a stack, the combination with anupper smoke consumer section within the stack, comprising two circularsections one above the other, the lower one being of a larger diameterthan the upper one and having outlet openings for directing jets ofsteam upwardly in cylindrical formation upon the outside of andconcentric with similar jets of steam directed upwardly from the uppercircular pipe, a lowermost blower section within the stack at the basetherof comprising a circular pipe with outlet openings for directingjects of steam upwardly and through the stack in cylindrical formationon the outside of and concentric with the first two cylindrical jets ofsteam, said latter cylindrical formation of jets of steam from thelowermost blower acting to consume the black smoke and soot and at thesame time discharge the smoke in general from the stack, a steam pipeoperatively connecting to all three of the circular pipe blower sectionsin the stack, said steampipe being on the exterior of the stack andadapted for conveying steam to all three blower sections, meansassociated with the steam pipe at a point below the blower section atthe base of the steam for shutting oif steam to all three blowersections, and means associated with the steam pipe at a point just abovethe blower section at the base of the stack for shutting off steam tothe first two circular blower sections.

In testimony whereof they aflix their signatures.
